NPDES Permit NCG500322
Gaston County
Dear Mr. Smyer:
Please find enclosed the Compliance Evaluation Inspection for the site visit conducted on July 3, 2018 by
Ori Tuvia. Your cooperation during the site visit was much appreciated.
The main area of concern noted in the inspection was the records reviewed were incomplete for calendar
year 2017 and the first half of calendar year 2018 by failing to record pH and flow.
Since the previous inspection, the facility has been tied-in to the City collection system (on April 1,2018)
and no longer discharges for surface waters. As such,the facility no longer requires the NPDES discharge permit,
and may request to have the permit rescinded. Please contact Mr. Derek Denard at derek.denard-.0 ncdenr.gov or
at:
N. C. Division of Water Resources
Water Quality Permitting Section -NPDES
1617 Mail Service Center
Raleigh,NC 27699-1617
Due to the fact the subject facility is no longer discharging to surface waters, the Mooresville Regional
Office will not pursue any further action on the violations listed provided that this Office receives a copy of the
request for recession of permit NCG500322 within fifteen (15) days of your receipt of this correspondence. You
should be aware that the subject facility will be continue to be considered in violation until such time as the
requested permit rescission documentation is received and therefore could subject the facility to the possible
assessment of civil penalties.

Dear Mr. Smyer:
Please find enclosed the Compliance Evaluation Inspection for the site visit conducted on January 24, 2017
by Ori Tuvia. Your cooperation during the site visit was much appreciated.
The facility has shown some notable improvement since the last inspection including preforming all
required sampling. The main area of concern is the high pH sampling results, 10.3,which exceeds the permitted 6-9
range.
Because the subject facility is deemed to be in non-compliance with terms and conditions contained in
NPDES Permit No. NCG500322 you are required to respond to this Office, in writing, stating what measures will be
undertaken to immediately resolve the non-compliance issues noted above, within fifteen days of your receipt of
this correspondence.You should be aware that until full compliance is achieved with all Division regulations and
permit conditions, the subject facility will be considered to be in violation and could be subject to the possible
assessment of civil penalties.
If you have any questions, please contact Ori Tuvia at [phone], or via email at [e-mail].

Russell,
Thought I'd keep you in the loop with the results of water samples.. Dallas sample is reading pH 10.6 and after diluting it
twice with pure water still read pH 10.3 (very Alkaline).
Kimbrell sample is reading pH 11.4 and after diluting it twice with pure water read pH 11.2 (also very alkaline). Reading
was done through an accurate pH meter(Accumet AB 15)and it was calibrated prior testing those samples. My thoughts
are just speculations,that this water is running through piping or certain area that's releasing alkaline ions in it..
concrete might contain limestone or the soil can be alkaline in certain areas!! Many reasons could cause that pH change!
Hope that helps,and I'll be glad in helping with any testing you need.
Regards,
DiGaston College

Dear Mr. Smyer:
Please find enclosed the Compliance Evaluation Inspection for the follow-up site visit conducted on May
17, 2016 by Ori Tuvia of the Mooresville Regional Office. Your cooperation during the site visit was much
appreciated.There was much improvement since the last inspection conducted on March 9, 2016.The following
violations still need to be addressed:
- pH sample results recorded for the boiler blow-down were above the permitted range (6-9).
- Chemical Oxygen Demand (COD) needs to be properly sampled and delivered in timely manner to be
analyzed.
- Sampling was done by Cascade Water.Service. No calibration logs were available for review.
- No Biocide/Chemical Treatment Worksheet form was available for review during the inspection. The
facility was missing the Worksheet during the previous inspection that was conducted on 11/2/2012 by
Wes Bell.
You are requested to provide the following information, by June 15, 2016, relative to the inspections
conducted on March 9, 2016 and May 17, 2016:
- Proper sampling results for the boiler blowdown (including COD). Must include calibration log
and Chain of Custody.
- A plan as to how the facility will lower pH.
- A Biocide worksheet for each chemical used in the boiler.
Mooresville Regional Office
I nratinn•Ain Fact r:antar Ava Chico 3n1 Mnnracvilla Nr.. 7R11c

Pr,
As was discussed during the inspection,the facility is encouraged to discuss with the sewer provider the
possibility of connecting the boiler blow-down (and the cooling towers if necessary)to the sewer system. If the
discharges are connected to the sewer, the facility will no longer need to maintain this permit (NCG500322).
Following a written request and subsequent approval for rescission, you will no longer be bound by the
requirements and conditions of this permit.
Please be advised this letter is a Notice of Continuing Violation. If all issues are not resolved or addressed
by June 15, 2016, the next step will be the issuance of a Notice of Violation and Notice of Recommendation for
Enforcement (NOV/NRE).
A Notice of Violation and Notice of Recommendation for Enforcement, pursuant to G.S. 143-215.6A,may
result in a civil penalty of not more than twenty-five thousand dollars ($25,000.00) per day, per violation and
may be assessed against any person who violates or fails to act in accordance with the terms, conditions, or
requirements of any permit issued pursuant to G.S. 143-215.1.
If you have any questions, please contact Ori Tuvia at (704) 663-1699, or via email at
[e-mail].

Gaston College/ Boiler Plant
NPDES Permit NCG500322
Gaston County
Dear Mr. Smyer:
Please find enclosed the Compliance Evaluation Inspection for the site visit conducted on March 9,
2016 by Ori Tuvia and Roberto Scheller of the Mooresville Regional Office. Your cooperation during the site
visit was much appreciated. The following observations were documented during the inspection:
- Missing sampling event of the boiler blow-down for the second half of 2015.
- PH samples recorded for the boiler blow-down were above the permitted range (6-9).
- Chemical Oxygen Demand (COD) was not sampled as required in the permit.
- Sampling was done by Cascade Water Service. No calibration logs were available for review.
- No Biocide/Chemical Treatment Worksheet form was available for review during the inspection. The
facility was missing the Worksheet during the previous inspection that was conducted on 11/2/2012 by
Wes Bell.
- Permittee could not indicate if cooling tower discharges into the city sewer or into the storm water
system.
Please be advised that staff of this office will conduct a follow-up inspection 60 days from notification
of your receipt of this correspondence.
Mooresville Regional Office
Location:610 East Center Ave.,Suite 301 Mooresville,NC 28115

You are requested to provide the following information, by 60 days from notification of your receipt of
this correspondence, relative to the inspection conducted on March 9, 2016:
J - Sampling results for the boiler blowdown (including COD). Must include calibration log and
Chain of Custody.
A plan as to how the facility will lower PH.
- A Biocide worksheet for each chemical used in the boiler.
- Verify where the boilers and cooling towers discharge.
As was discussed during the inspection the facility is encouraged to discuss with the sewer provider the
possibility of connecting the boiler blow-down (and the cooling towers if necessary)to the sewer system. If
the discharges are connected to the sewer,the facility will no longer need this permit (NCG500322).
If you have any questions, please contact Ori Tuvia at [phone], or via email at
[e-mail].

Wes,
I have had several conversations with Shawn Smith with Cascade Water Services who provides
our boiler water treatment services. I had asked him to fill out the forms referenced in the
NCDENR letter (attached). After reviewing the information within Cascade they have sent MSDS
and PBS info on the only two chemicals used in the boilers (attached) but have not filled out
the form since it specifically references biocide multiple places throughout the form and no
biocide is used for this facility.
I have attached (below) the last e-mail from Cascade as well for reference.
I have no e-mail reference for the Regional Office so I am only copying you at this point.

CLOSED CHILL/HOT WATER SYSTEMS
Aqualine employs state of the an water treatment programs in necordnnce with current
industry standards and equipment manufacturers recommendations:
Corrosion Control: Aqualine will routinely test and make recommendations to
control corrosion inhibitor at proper levels. Normally the hot water
system will require higher levels than chill water Tests for pH,
total dissolved solids (TDS),iron and corrosion inhibitor tracer
(usually nitrite or molybdate)will be provided.
Microbiological: Aqualine will periodically test systems for m crobiolog!cal activity
Control if system tests indicate that this is required. If appropriate, a
biocide compatible with existing inhibitor will be added.
Other Tests: Aqualine highly recommends installation of corrosion coupon racks
Recommendations (at least one test specimen per recirculating chill/hot system)to
monitor the effectiveness of the treatment program. Specimens may
be analyzed by an independent laboratory for objectivity.
Aqualine will routinely test systems containing ethylene or
propylene glycol for proper concentration (%by volume), freeze
point, inhibitor level (if applicable),and visual clarity.

Gaston College is applying for a general permit for the
discharge of cooling water and boiler blowdown water generated at
the facility. There are three distinct points that eventually
discharge into an unnamed tributary to Long Creek. Two of them are
cooling water discharges and a third is boiler blow down. The
boiler blowdown discharge point could not be located by the
facility's contact person, nor was data available concerning the
volume of the discharges. Mr. Steve Hall, Systems Planning &
Maintenance Supervisor for Gaston College, was advised to locate
the discharge point for the boiler blowdown and to provide this
Office with the volume of discharges.
It should be noted that the application was not signed by an
appropriate official with Gaston College.
It is recommended the subject permit be issued once the above
concerns have been addressed.

Dear Mr. High:
This letter is in reference to your application for coverage under the General Permit
for Single Family Residences, which was received in our offices on April 22, 1996. On
January 14, 1997, the Division notified you that we required additional information on this
application by January 31, 1997 prior to completing our review. Some of the information
was faxed to our offices on January 30, 1997. However, all of the concerns were not
addressed.
Although you submitted a narrative description of the discharge points, we still
require a site map detailing the proposed discharge points--not only where they are located,
but also the drainage pathways of the discharge water. Also,the Division required and
requested that the application be signed by an appropriate official of the college with
knowledge of the systems requiring this permit. Neither of these items were submitted to
us.
Enclosed please find the application materials submitted. Application fees are non-
refundable according to North Carolina Administrative Code 15A NCAC 2H.0105 (b)(1).
Discharging without a valid NPDES permitmi will be subject to a civil penalty of up to
$10,000/day of operation. If you have questions regarding this matter,please contact
Susan Robson at [phone], ext. 551.

Dear Permittee:
The facility listed above is covered under NPDES General Permit NCG500000. NCG500000 expires
on July 31,2007. Federal(40 CFR 122.41)and North Carolina(15A NCAC 2H.0105(e))regulations require
that permit renewal applications must be filed at least 180 days prior to expiration of the current permit. If
you have already mailed a renewal request,you may disregard this notice.
To satisfy this requirement,the Division must receive a renewal request postmarked no later than
February 1, 2007. Failure to request renewal by this date may result in a civil penalty assessment. Larger
penalties may be assessed depending upon the delinquency of the request. This renewal notice is being sent
well in advance of the due date so that you have adequate time to prepare your application.
If any discharge previously covered under NCG500000 will occur after July 31, 2007,the
CoC must be renewed. Discharge of wastewater without a valid permit would violate North Carolina
General Statute 143-215.1; unpermitted discharges of wastewater may be assessed civil penalties of up to
$25,000 per day.
If all discharge has ceased at your facility and you wish to rescind this CoC [or if you have other
questions],contact me at the telephone number or e-mail address listed below.
Sincerely,

empties onto the ground and runs off into a small creek which
empties into Long Creek. The third cooling tower empties into
the sewer line that was install many years ago.
Both of the boilers have a boiler blow-down which drains into a
pipe line that goes into a holding basin on campus and then feeds
into the creek and then into Long Creek.
Should you have any questions or need additional information

PART IV - EVALUATION AND RECOMMENDATIONS
Gaston College is applying for a general permit for the
discharge of cooling water and boiler blowdown water generated at
the facility. There are three distinct points that eventually
discharge into an unnamed tributary to Long Creek. Two of them are
cooling water discharges and a third is boiler blow down. The
boiler blowdown discharge point could not be located by the
facility' s contact person, nor was data available concerning the
volume of the discharges . Mr. Steve Hall, Systems Planning &
Maintenance Supervisor for Gaston College, was advised to locate
the discharge point for the boiler blowdown and to provide this
Office with the volume of discharges .
It should be noted that the application was not signed by an
appropriate official with Gaston College.
It is recommended the subject permit be issued once the above
concerns have been addressed.
